Patent JP-H04315487-A (JP)
Title: Semiconductor laser
Inventor: ENDO KENJI
IPC: H01S5/00
Filed: 1991-04-15
Abstract: PURPOSE:To suppress local generation of heats on a reflecting surface and in an active layer near the surface by forming a compression stress thin film on the surface. CONSTITUTION:A polycrystalline GayIn1-yP10 is formed on a resonator reflecting surface 9. In this case, a lattice constant of the layer 10 is smaller than that of a GaAs active layer 3, and a compression stress is applied to the layer 3 of the surface 9. Since the change rate of a forbidden band of the layer 3 to the applied stress is 10<-5>eV-kg.cm<-2>, an increase in the forbidden band width up to 10meV can be realized by the application of the stress up to several 10<9> dyne/cm<2>. This is a sufficient value to reduce an injected carrier density and the absorption factor of an oscillated light. Thus, the local generation of the heat for causing the deterioration of the layer 3 of the surface 9 can be reduced.

Filed: 1989-03-31
Abstract: PURPOSE:To keep safety of stopping a motor by providing a first control means which operates an actuator after an manual operation means is set at a neutral stopping position gradually to the side of stopping, and a second control means which sets a plurality of different stopping operational characteristics, and a changeover means. CONSTITUTION:A plurality of relations between electric current values and time with respect to a solenoid proportional pressure reducing valve 3 are set after the time a1 when an operational lever 14 is set in a neutral stopping position N. A switch as a changeover means 15 is provided in order to select characteristics A1 to A3. When the characteristic A1 is selected by the switch 15 and the lever 14 is set in the neutral stopping position N, a hydraulic motor 13 is decelerated comparatively slowly and a swivel base is stopped with smoothness. On the other hand, when the characteristic A3 is selected and the lever 14 is set in a neutral position N, the motor 13 is decelerated comparatively speedily and the swivel base is stopped rapidly. Working efficiency is then improved while keeping the stopping safety of the motor 3.

Title: Rotary head assembly for magnetic recording and reproducing device
Inventor: FURUKAWA HIROMICHI
IPC: G11B15/61
Filed: 1986-04-08
Abstract: PURPOSE:To secure the even floating value of a tape type recording medium by forming a spiral group at a part of the range reaching an exit part from an entrance part where the recording medium is wound around a fixed cylinder so that the air intake is approximately reduced in a linear form. CONSTITUTION:When a rotary cylinder 2A is turned toward an arrow head 13, the air is absorbed through a spiral group 504 and therefore a tape type recording medium 9 is pulled toward cylinders 2A and 5A. Then the air intake is decreased toward an exit part C from an entrance part A in an approximately linear form. As a result, the floating value of the medium 9 is approximately even from the part A through the part C. Then the deformation of the medium 9 can be approximately kept in an even state over the entire area between both parts A and C at a point in the vicinity of a head chip 101. Thus the stable transmission of signals is secured between the chip 101 and the medium 9.

Title: Walking farm machine
Inventor: KITA TAKESHI
IPC: B60K20/02
Filed: 1979-06-29
Abstract: PURPOSE: To simplify the transmission operation by controlling oil flow of the transmission gear with an electric switch.  
     CONSTITUTION: This farm machine is equipped with a hydraulic circuit composed of a transmission gear PS including 5-port 3-position switching and 4-port 3-position switching electromagnetic direction valves VA and Vb and a hydraulic multiplate clutch and an electric circuit to control the oil flow of the transmission gear PS with a switching element. By the switching operation of the electric circuit, solenoids S1 to S3 and SR are excited to switch the oil flow supply circuit to the transmission gear. In this manner, when a transmission command is given to shift the position from the advance to retraction, the transmission can be made to retract via the neutral position. This transmission enables shift to the traction once after the machine is halted, thereby improving confortability eliminating impact on operators.

In this respect, the device 3 which is easily affected by the dust is placed at a lower position distant from the part 4 and the anode 5. Thus the influence of the dust on the device 3 can be reduced. The device 3 is also kept distant from a tuner circuit 6 that treats the weak signals. As a result, both the influence of dust on the device 3 and the influence of noise on the circuit 6 can be reduced.

Abstract: PURPOSE:To decide optimum transmission speed by one training by providing a mean square error calculation circuit calculating a mean square error during the reception of a prescribed scramble data to an equalizer so as to measure the degree of line equalization. CONSTITUTION:The number of times of accumulation N is set to '8' and '48' by using the CCITT modem recommendations V27ter segment 5 and V29 segment 4. In case of using a V29 modem at first an error rate versus S/N curve of the V29 modem is plotted to obtain the S/n with respect to the user allowable error rate and it is referred to as a threshold level TH. Thus, in the actual facsimile communication, when the value QL is smaller than the TH, 9600bps as the optimum transmission speed is adopted and when larger, 7200bps is selected as the optimum transmission speed. Thus, one training is enough to determine the optimum transmission speed.
